'lwo or more plates roo or washers 26, which are similar in form to the recess 25, are arranged transversely therein, fitting snugly and incapable of rotating. These washers are each provided with a notch 27, in alinement with the passage 19, and between each two washers is arranged a circular ring-like tumbler 28, likewise provided with a notch 29, adapted to register with the notches of the washers. The inner edge of each tumbler is notched, as at 30, one of said notches being adapted to receive a projection 31, formed on a ring 32, which is to be sprung into the tumbler between the inner edges thereof. An inner projection 33 is also formed on this ring, and this projection is provided with a laterally-extending pin 34. These pins are adapted to engage with the projections 33 of the adjacent tumblers, causing them to turn therewith. It is obvious that when motion is imparted to one of the tumblers the notches 29 thereof will through proper manipulation be brought into aline'ment with the passage 19L and notches 27 of the washers 26, permitting the arm or dog 24 to fall therein, thereby locking them together.

Bearing against the guide 20 is a disk 35, provided with a pin 36, adapted to engage with the projection 33 of the adjacent tumbler. This disk is notched in its outer edge to correspond with the tumblers and is adapted to be locked thereto by the dog 24 when all of the notches are in alinement. Secured to this disk is the endof a spindle 37, which passes through the stem 13 and the door to which the lock is secured, a knob 38 being secured to the opposite end. That portion of the spindle which is outside of the stem 13 is preferably square in cross-section and is adapted to be received by a square passage 39, formed in a wheel 40, mounted within the casing. 1 and provided in its edge with recesses or concavities 41, as shown.

Slidably mounted within the casing and properly guided by lugs 42 is a rack 43, one end of which bears upon the edge of the wheel 40, while the teeth 44, formed near the opposite end, are adapted to engage with a cog 45, secured to one end of a shaft 46, revolubly mounted within the casing and provided with suitable clappers for striking a bell 47, secured to the said casing. It will be seep that this rack will be held in contact with .the wheel 40 at all times by force of gravity. If desired, two racks and cogs may be placed within the casing, as shown in Fig. 3, thereby permitting the lock to be inverted without destroying the efficiency of the alarm. A dial or disk 48 is secured to the outer face of the door and about the spindle 37, and this may be provided with suitable numerals or letters, (itc. A pointer (not shown) is secured to the spindle and adapted to turn therewith.

In operation by simply turning the knob 14 in either direction the retractor-plate 12 will bear back upon one of the arms 7 of the bolt and retract the same. When pressure is removed, the spring 10 will return it to its norsaidv knob to revolve .therewith and turn the retractor-plate 12, which will withdraw the bolt, as is obvious. While the knob 38 is being turned back and forth the rack 43 is moved up and down by the revolution of wheel 40, causing the cog 45 to revolve, and thereby sounding an alarm. 1t will be understood that the combination may be readily changed by removing one or ymore of the rings 32 and replacing the projections 31 in different notches 30 of the tumblers. dog 24 by means of thumb-piece 23 and turning the knob slightly the door will become locked and cannot be opened from without unless the knob 38 is again turned to the proper combination.

In the foregoing description we have shown the preferred form of our invention; but we do not limit ourselves thereto, as we are aware that modifications may be made therein without departing from the spirit or sacrificing the advantages thereof, and we therefore reserve the right to make such changes as fairly fall within the scope of our invention.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a lock the combination with a spindle, of a tumbler secured to one end thereof, a second tumbler engaging therewith, a washer between the tumblers and secured to a knob inclosing the same, and means 'for locking said tumblers and washer together.

2. In a lock thecom bination with a spindle, of a notched tumbler secured thereto, a second tumbler engaging therewith and provided with a similar notch, a notched washer between the tumblers and secured to a knob inclosing the same, and a vertically-movable dog adapted to engage with said notches when brought into alinement.

3. In a lock the combination with the casing, of a spindle therein, a toothed Wheel secured thereto, a gravity-seated slide contacting at its end with the periphery of said.

wheel, an alarm, and means for sounding said alarm from the slide.

4. In a lock the combination with the spindle; of a stem loosely mounted thereon; a ret'ractor-plate secured to the stem; a sliding plate havingarms adapted to be engaged and retracted by said plate; tu mblers; and a dog, said bolt adapted to be operated by the spindle and retractor-plate upon turning the same in either direction to predetermined points.

6. A lock comprising a casing, a spind le, a toothed Wheel secured thereto, a sliding rack contacting with the periphery of the Wheel and adapted to engage with a cog for operating an alarm, a tumbler secured to the end of the spindle, a stem loosely mounted on the spindle, a knob secured thereto and having a Washer fixed therein, a dog for locking said tumbler and Washer together, a retractor-plate secured to the stem, a sliding tension and a laterally-extending,r pin thereon..
